Carrier 00PPG000471600A Flow Switch Level Detector Assembly

The Carrier 00PPG000471600A is a genuine OEM flow switch and level detector engineered for dependable flow detection and system protection in Carrier HVAC, hydronic, and transport refrigeration applications. It monitors fluid movement through piping systems to confirm adequate flow before allowing downstream components to operate, serving as a critical safeguard in chillers, pumps, and heat exchangers against low-flow or no-flow conditions. This device detects the presence and movement of liquid within piping lines by sensing changes in flow conditions through an internal mechanical or magnetic sensing element. When fluid begins moving through the pipe, the sensing mechanism responds by shifting position, producing an electrical signal that indicates flow status to the control system. The part replaces legacy Carrier part number HR12BA011 and carries NSN 6680-01-632-3170 for military and government procurement.
